| fibronectin laminase | <enzyme> Fibronectin fragment which has been activated by calcium chloride to produce a calcium-dependent proteolytic activity that splits preferentially laminin and denatured collagen type 1; cleaves the ala-gly bond in the sequence gpagpr; the arginine residue in position p3' is important for this cleavage Registry number: EC 3.4.99.- Synonym: fn-laminase (26 Jun 1999) |

| receptors, fibronectin | Specific sites or molecular structures on or in cells with which fibronectins react or to which they bind. Studies have shown that these receptors function in certain types of adhesive contact as well as playing a major role in matrix assembly. These are the traditional fibronectin receptors, also called vla-5 receptors or alpha 5 beta 1 integrins. There are also other integrins that bind fibronectin, including alpha v beta 1.

| plasma fibronectin | A circulating a2-glycoprotein that functions as an opsonin, mediating reticuloendothelial and macrophage clearance of fibrin microaggregates, collagen debris, and bacterial particulates, protecting microvascular perfusion and lymphatic drainage. (05 Mar 2000) |
| fibronectin | <protein> Glycoprotein of high molecular weight (2 chains each of 250 kD linked by disulphide bonds) that occurs in insoluble fibrillar form in extracellular matrix of animal tissues and soluble in plasma, the latter previously known as cold insoluble globulin. The various slightly different forms of fibronectin appear to be generated by tissue specific differential splicing of fibronectin mRNA, transcribed from a single gene. Fibronectins have multiple domains that confer the ability to interact with many extracellular substances such as collagen, fibrin and heparin and also with specific membrane receptors on responsive cells. Notable is the RGD domain recognised by integrins and two repeats of the EGF like domain. Interaction of a cells fibronectin receptors (members of the integrin family) with fibronectin adsorbed to a surface results in adhesion and spreading of the cell. (18 Nov 1997) |
| fibronectin hexapeptide N-acetylgalactosaminyltransferase | <enzyme> Enzyme from foetal and malignant tissues recognizing the sequence val-thr-his-pro-gly-tyr in fibronectin Registry number: EC 2.4.1.- Synonym: udp-galnac-vthpgy alpha-galnac transferase, hexapeptide-galnac-transferase (26 Jun 1999) |
